Description

Technical Field

[0001] The utility model relates to the technical field of heater overflow prevention, in particular to an overflow prevention electrode, a heater top cover and a heater. Background Art

[0002] Heaters, such as soymilk machines and food processors, are usually equipped with anti-overflow electrodes to prevent liquid from overflowing during heating. Anti-overflow electrodes usually have two structures, one is a single-needle structure and the other is a double-needle structure.

[0033] In the related art, whether it is a single-needle or double-needle anti-overflow electrode, it is impossible to avoid water or foam hanging on the anti-overflow electrode due to the surface tension of the liquid or foam, causing conduction resistance between the two poles of the electrode, thereby judging overflow when there is actually no overflow, affecting the normal heating control program.

[0034] In order to avoid misjudgment of overflow caused by water or foam hanging on the insulating structure, the embodiments of the present disclosure provide an anti-overflow electrode, a heater top cover and a heater.

[0035] Figure 1 is a schematic cross-sectional view of an anti-overflow electrode according to an exemplary embodiment. Figure 1 As shown, the anti-overflow electrode is a single-needle bipolar structure, including: a first electrode 1 , an insulating layer 2 and a second electrode 3 , wherein the insulating layer 2 is used to isolate the first electrode 1 from the second electrode 3 .

[0036] In the embodiment of the present disclosure, the first electrode 1 is a columnar structure, the insulating layer 2 is sleeved outside the first electrode 1, and the second electrode 3 is a tubular structure, sleeved outside the insulating layer 2, and the first electrode 1 and the second electrode 3 are isolated by the insulating layer 2. The length of the first electrode 1 is greater than that of the second electrode 3, the lead wire connected to the first electrode 1 is used to connect to the heater circuit, and the lead wire connected to the second electrode 3 is used to connect to the heater circuit, one of the first electrode 1 and the second electrode 3 is a positive electrode, and the other electrode is a negative electrode, the first electrode 1 and the second electrode 3 are both made of food-grade electrode materials, and the insulating layer 2 is made of food-grade anti-corrosion insulating materials.

[0037] The insulating layer 2 includes an annular insulating structure 201, which is arranged around the first electrode 1; the second electrode 3 is located on one side of the annular insulating structure 201, and the horizontal cross-sectional diameter of the annular insulating structure 201 increases in a direction away from the second electrode 3; the annular insulating structure 201 is used to guide the liquid suspended on the anti-overflow electrode.

[0038] In the embodiment of the present disclosure, the annular insulating structure 201 is arranged around the middle of the first electrode 1, the second electrode 3 is located above the annular insulating structure 201, and the horizontal cross-section of the annular insulating structure 201 is a circular ring, and the diameter of the circular ring increases in the direction away from the second electrode 3. The water or foam hanging on the second electrode 3 and the annular insulating structure 201 flows downward under the action of gravity, and the water or foam hanging can flow in the direction away from the first electrode 1 through the guidance of the annular insulating structure 201, thereby avoiding misjudgment caused by the conduction between the first electrode 1 and the second electrode 3 due to the water or foam hanging.

[0041] Based on the above, it can be known that in the embodiment of the present disclosure, by setting the annular insulating structure 201 as an annular umbrella-shaped structure with a certain curvature, the water or foam can be directed away from the first electrode 1 through the diversion effect of the umbrella-shaped structure, thereby avoiding misjudgment of overflow due to conduction between the first electrode 1 and the second electrode 3 caused by water or foam; when the anti-overflow electrode is in an inverted state, the conductive end of the first electrode 1 faces upward, and the water or foam thereon can be received by the concave surface of the annular umbrella-shaped structure, avoiding flowing to the second electrode 3 and causing misjudgment of overflow.

[0044] Based on the above, it can be known that in the embodiment of the present disclosure, by setting the annular insulating structure 201 to an annular trumpet-shaped structure, the water or foam can be directed away from the first electrode 1 through the diversion effect of the slope of the trumpet-shaped structure, thereby avoiding misjudgment of overflow due to conduction between the first electrode 1 and the second electrode 3 caused by water or foam; when the anti-overflow electrode is in an inverted state, the conductive end of the first electrode 1 faces upward, and the water or foam thereon can be received by the concave surface of the annular trumpet-shaped structure, avoiding flowing to the second electrode 3 and causing misjudgment of overflow.

[0045] In an optional embodiment, if Figure 2 As shown, the insulating layer 2 also includes: a target insulating structure 202; the target insulating structure 202 is between the first electrode 1 and the second electrode 3; the inner wall of the target insulating structure 202 is in contact with the first electrode 1, the outer wall of the target insulating structure 202 is in contact with the second electrode 3, and one end of the target insulating structure 202 is connected to the annular insulating structure 201.

[0046] In the disclosed embodiment, the target insulating structure 202 is a tubular structure, which is located between the first electrode 1 and the second electrode 3 to isolate the two electrodes. The inner wall of the target insulating structure 202 is in contact with the first electrode 1, and the outer wall of the target insulating structure 202 is in contact with the second electrode 3. The end of the target insulating structure 202 extending out of the annular insulating structure 201 close to the first electrode 1 is connected to the annular insulating structure 201.

[0047] Based on the above, it can be known that in the embodiment of the present disclosure, the second electrode 3 can be completely isolated from the first electrode 1 by the annular insulating structure 201 and the target insulating structure 202 of the insulating layer 2 to prevent the first electrode 1 from being electrically connected to the second electrode 3 .

[0048] In a second aspect, the present disclosure also provides a heater top cover, comprising the above-mentioned anti-overflow electrode.

[0049] In the disclosed embodiment, the overflow-proof electrode is mounted on the top cover of the heater, and one end of the electrode 2 is located inside the top cover of the heater.
